Significado en lenguaje sencillo
A screener applies explicit conditions to stored/source-backed fields for one exchange or chosen universe. A match describes available inputs at that time, not future performance.
1. Select exchange and universe. 2. Add conditions and indicator overrides. 3. Review units and unavailable behavior. 4. Run. 5. Add optional result columns. 6. Open matches for evidence. 7. Save only the exact rule you reviewed.
A rule RSI(14) < 30 and volume > 1,000,000 returns only rows with both computed inputs. A listing with missing volume is unavailable and must not pass as volume 0.
More matches mean more rows satisfy the rule, not a stronger signal. Positive/negative fields retain their metric meaning. Zero can be genuine; — means not evaluated or unavailable.
A genuine source-reported or calculated zero is displayed as 0. Unavailable (—) means verified evidence is absent, unsupported, stale or not computable; it is never silently changed to zero.
Look-ahead bias, stale data, survivorship bias, unlike currencies and mismatched indicator conventions can mislead. Backtests are historical observations, not predictive accuracy.
Exchange universes, currencies, sessions, price scales, filings and technical coverage differ. Never let an empty international universe fall back to NSE symbols.
Continue with Charts and indicators, Exchange and universe, Data freshness, and glossary terms RSI, MACD, moving average, volume and candlestick pattern.
